摘要

东非大裂谷系统(EARS)是大陆裂谷的一个典型例子,其标志性地形特征是由构造和气候力量的相互作用而形成的。本文综述了过去几十年来对非洲断裂带高原地貌的形态构造研究(近期研究),尤其侧重于其内部和边缘,并强调了这些研究在促进我们对地貌演化的理解方面所起的关键作用。本文回顾了 EARS 的地质研究遗产,并深入探讨了近期的形态构造研究,这些研究通过先进的热时学和地形分析,量化了高原切入、掘起和隆起的速度和模式。此外,该综述还指出了一些关键的未决问题,如高原地形的起源--是火山活动还是地幔羽流的影响,并探讨了这些高原如何在潮湿的渐新世时期保持高海拔而没有明显的切削。本文所描述的最新工作以及遗留的观点将继续完善我们对 EARS 的地质认识,并对全世界的研究产生更广泛的影响。

Review of morphotectonic studies in the East African Rift System: Insights from legacy research to modern advances
The East African Rift System (EARS) is a prime example of continental rifting, characterized by its iconic topographic features, which are significantly shaped by the interplay of tectonic and climatic forces. This review synthesizes past decades of morphotectonic studies (recent studies) on the plateau landscapes of the EARS, focusing particularly on their interiors and margins, and highlights their crucial role in advancing our understanding of landscape evolution. The paper revisits the legacy of geologic research in the EARS and delves into recent morphotectonic studies that quantify the rates and patterns of plateau incision, exhumation, and uplift through advanced thermochronological and topographic analyses. Additionally, the review identifies key unresolved questions, such as the origins of the plateau topography–whether from volcanic activity or mantle plume influence and explores how these plateaus maintained high elevations during the humid Oligocene Epoch without significant incision. The recent work described in this paper alongside legacy perspectives, continues to refine our geological understanding of the EARS, with broader implications for studies worldwide.

期刊介绍: The Journal of African Earth Sciences sees itself as the prime geological journal for all aspects of the Earth Sciences about the African plate. Papers dealing with peripheral areas are welcome if they demonstrate a tight link with Africa. The Journal publishes high quality, peer-reviewed scientific papers. It is devoted primarily to research papers but short communications relating to new developments of broad interest, reviews and book reviews will also be considered. Papers must have international appeal and should present work of more regional than local significance and dealing with well identified and justified scientific questions. Specialised technical papers, analytical or exploration reports must be avoided. Papers on applied geology should preferably be linked to such core disciplines and must be addressed to a more general geoscientific audience.
